“I requested some details on-line from Critical Power Supplies for their 24VDC UPS systems, I was impressed from their prompt reply, the close attention to detail and their going out of their way to provide me with simplified diagrams they had to produce just for my use. Definitely a very efficient and effective but most of all friendly and responsive team of people. Thanks a lot guys.” Said Ackey Chrysovulos, Chief Resident Engineer, ACE Int’l OMAN.

“Thank you so much for helping with this – can’t tell you how much I appreciate it!”

Product arrived on time and did exactly what you said it would. Brilliant!”

The installation occurred exactly as planned and thank you for providing the additional rack and PDU’s – ordering them from you saved us time and energy.

As an overseas customers its brilliant knowing we can reach you 24×7 – it feels like there is no time difference."

“Thank you for helping us to save energy and reduce our carbon footprint. The old three phase UPS was very inefficient and it was great knowing you could take it away to be recycled as part of the installation service.”
